element-ui使用导航栏跳转路由的用法详解

最近初学vue,试着做一个小项目熟悉语法与思想,其中使用elemen-ui的导航栏做路由跳转切换页面。下面记录一下学习过程
element-ui引入vue项目的用法参考element官网
首先复制官网的例子,在这基础上再修改成我们想要的样子。
<el-menu :default-active="activeIndex" class="el-menu-demo" mode="horizontal" @select="handleSelect"> <el-menu-item index="1">处理中心</el-menu-item> <el-submenu index="2"> <template slot="title">我的工作台</template> <el-menu-item index="2-1">选项1</el-menu-item> <el-menu-item index="2-2">选项2</el-menu-item> <el-menu-item index="2-3">选项3</el-menu-item> <el-submenu index="2-4"> <template slot="title">选项4</template> <el-menu-item index="2-4-1">选项1</el-menu-item> <el-menu-item index="2-4-2">选项2</el-menu-item> <el-menu-item index="2-4-3">选项3</el-menu-item> </el-submenu> </el-submenu> <el-menu-item index="3" disabled>消息中心</el-menu-item> <el-menu-item index="4"><a href="https://www.ele.me" rel="external nofollow" target="_blank">订单管理</a></el-menu-item> </el-menu> <script> export default { data() { return { activeIndex: '1' }; }, methods: { handleSelect(key, keyPath) { console.log(key, keyPath); } } } </script>
属性:
* default-active:表示当前active的菜单项的编号
* index:类型为字符串,在每一个el-menu-item组件上都有一个编号,给default-active标记
使用菜单栏进行路由跳转:
<el-menu :default-active="this.$router.path" router mode="horizontal"> <el-menu-item v-for="(item,i) in navList" :key="i" :index="item.name"> {{ item.navItem }} </el-menu-item> </el-menu>
数据:
data() { return { navList:[ {name:'/findProject',navItem:'发现项目'}, {name:'/communityActivity',navItem:'社区动态'}, {name:'/publishProject',navItem:'发布项目'}, {name:'/personalCenter',navItem:'个人中心'}, {name:'/manageCenter',navItem:'管理员中心'}, ] } }
路由:
export default new Router({ routes: [{ path: '*', redirect: '/findProject' }, { path: '/findProject', name: 'findProject', component: findProject }, { path: '/communityActivity', name: 'communityActivity', component: communityActivity }, { path: '/publishProject', name: 'publishProject', component: publishProject }, { path: '/personalCenter', name: 'personalCenter', component: personalCenter }, { path: '/manageCenter', name: 'manageCenter', component: manageCenter }] })
使用菜单栏进行路由跳转有几个注意点:
1. 在el-menu加上router
2. index必须绑定路由的path,参考上面的例子,'/'不能少
3. default-active设为当前路由(this.$router.path),这样在路由变化的时候,对应的menu-item才会高亮。
拓展知识:vue项目中的路由配置方法
公司的项目使用vue脚手架来搭建,是属于后台管理系统。功能页比较多,就使用vue路由来进行跳转;
个人比较习惯上面这种方式放置路由文件,并且使用懒加载的模式来配置,如下:
import Vue from 'vue' import Router from 'vue-router' //import Login from '.././views/login.vue' //import NotFound from '.././views/404.vue' //import Home from '.././views/index.vue' Vue.use(Router) export default new Router({ mode: 'history',//去掉#号 routes: [ { path: '/login', name: 'Login', component: resolve => require(['../views/login.vue'],resolve) }, { path: '/404', name: 'NotFound', component: resolve => require(['../views/404.vue'],resolve) }, { path: '/', redirect: '/default' }, { path: '/', name: 'Home', component: resolve => require(['../views/index.vue'],resolve), meta: {title: '自述文件'}, children:[ { path: '/default', component: resolve => require(['../components/default.vue'],resolve), meta: {title: '系统首页'} }, { path: '/set', component: resolve => require(['../components/set.vue'],resolve), meta: {title: '设置'} }, { path: '/user', component: resolve => require(['../components/user.vue'],resolve), meta: {title: '账户管理'} }, { path: '/member', component: resolve => require(['../components/memberList/memberList.vue'],resolve), meta: {title: '会员列表'} }, { path: '/baseCharts', component: resolve => require(['../components/charts/baseCharts.vue'],resolve), meta: {title: '会员分析'} } ] } ] })
在main.js中使用路由进行配置:
这样就可以在需要的地方使用路由了。
